This site is not for tutorials; I would suggest using Wikipedia and other internet resources for that.

If you have more specific questions, that's fine.

"...dbm, db, dbu..."

The 'B' in dB should be capitalized.

EMC testing is quite intricate, which is why they typically charge tens of thousands of dollars for such testing.
